TRUNK-LOCK.

Specification of Letters Patent.

Patented Jan. 6, 1914.

Application filed May 20, 1913. Serial No. 768,724.

To all whom it may concern:

Be it known that I, FRANK S. ALIANO, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Trunk-Locks, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to trunk locks, and more particularly to a type of swinging hasp trunk lock.

The main object of the invention is to provide a trunk lock having all of the safety factors of the ordinary tumbler lock, in which the safety element will consist of a rotary plate by means of which the bolt mechanism is actuated, said plate being capable of such structural variances as to permit a variance in the wards of diiferent keys, thus securing the same effects as are common in tumbler locks having different combinations A further object is to provide a lock of this character, wherein the rotary guard plate will be normally locked against rotation, and when actuated to a certain extent, or by a key having a ward of predetermined length, will be released, but if actuated to a greater or less extent will remain inoperative.

A still further object is to provide a lock wherein the guard plate, by means of a key, may be reciprocated to bring it to a position where it may be rotated, and be capable of subsequent rotation to effect the actuation of the bolt mechanism.

A still further object is to adapt my invention to a snap or self-closing lock, or one in which the bolts are normally projected beyond the cup, and are capable of reciprocation independently of, as well as under, the controlling mechanism therefor.

A still further object is to provide a lock, the design of which will be simple, the parts few in number and so arranged as to afford the desired factor of safety when the lock is in use, and in which said parts may be conveniently assembled and will not be readily disarranged or subject to such wear as to render the lock inoperative through repeated use. And a still further object is to provide a snap lock in which the cup and the parts contained therein will be so compact as to permit the use of the lock with a keeper plate secured to the outside of a trunk or other receptacle without the necessity for boring the body of said receptacle to accommodate the lower portion of the cup.

The invention consists primarily in a trunk lock embodying therein a hasp plate, a hasp pivoted thereto, a cup carried by said hasp, a guard plate, means whereby said plate is permitted to have a reciprocatory movement whereby it may be released, and a rotary movement, whereby said bolts are actuated, means controlled by said guard plate for actuating said bolts, cooperating means carried by said guard plate and said cup, whereby said guard plate is normally locked in relation to said cup, said guard plate having a way therein adapted to receive the wards of a key for reciprocating said plate, and a shoulder thereon adapted to be engaged by said wards for rotating said plate, and a keeper plate; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings :Figure l is an elevation of a lock embodying my invention, the hasp plate upon the cup being broken away to show the lock mechanism contained in said cup; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a top view of the cup with the controlling mechanism removed, a portion of the cup being broken away to disclose the construction of cup for cooperating with the guard plate and imparting a safety factor to the lock; Fig. A is a side view of the preferred form of rotary plate, guard plate and guard plate spring; and Fig. 5 is a bottom plan view thereof.

Like letters refer to like parts throughout the several views.

In the form of the invention shown in the drawings, a indicates an ordinary hasp plate; 6, an ordinary swinging hasp pivoted to said plate; and c, the cup secured to said hasp plate and containing the bolt and bolt actuating mechanisms. Slidably mounted within the cup 0 is a plurality of reciprocatory bolts (Z cl, which, in the form of the invention shown, are mounted upon the bot tom of said cup, the sides of said cup being pierced to permit the projection of these bolts therethrough. These bolts are preferably latch bolts, as shown, the adaptation of the invention illustrated in the drawings and herein described being of a snap,

latch or self-locking lock. The'bolts (Z CZ are enlarged within the cup as at (Pri to form stop shoulders for limiting the extent of projection of these bolts, and rearwardly of these extensions, I provide the laterally reduced angular stems d (Z which in the form of the invention shown have the twofold function of forming a spring seat for the springs e e, and shoulders adapted to cooperate with the bolt controlling mechanism for reciprocating said bolts by means of a key. The controlling means and the balanced condition secured by the springs e 6 will limit the bolts to a substantially lineal movement. The cup 0 may be, and preferably is, of the same diameter throughout, and rotatably mounted therein and resting upon the bolts (Z cl is the bolt controlling mechanism and guard mechanism; which has the twofold function of limiting the actuation of the lock to a key having certain characteristics, and by a rotary movement, simultaneously withdrawing said bolts within the cup to permit the raising of the hasp. This bolt controlling and guarding mechanism has two essential characteristics, to wit :-that through cooperating means carried thereby and by the cup 0, it is normally held inoperative while being capable of release by a reciprocatory movement under the key; and that after such reciprocatory movement, it is capable of rotation to retract the bolts. In the form of the invention shownrin the drawings, this mechanism comprises a rotary plate 7 having pendant studs f and f adapted to be seated within the angle of the angular stems d and (Z and by engagement with the shoulder formed by the short arm thereof, respectively, reciprocate said bolts, clearance beyond said angular stems being provided, as shown, to permit this reciprocation. Upon the upper surface thereof, this plate f is provided with the studs 9 9, upon which is mounted the combined reciprocatory and rotary guard plate h, having elongated slots h" [a therein adapted to pass over said studs 9 g. Said guard plate carries a stud h and mounted thereon and upon one of said studs as g is a bowed spring 2', exerting a constant tendency to restore said guard plate to normal, or to its locked position. Centrally thereof, the plates f and h are each pierced to accommodate the key bar rel j, which is of ordinary construction. If desired, a key stud may be used instead of a key barrel, the lock shown, however, beingv a flat key lock and not a barrel key lock which requires the key stud.

Centrally, and about the pierced central opening thereof, the plate 71. is provided with an opening forming the way alined wit-h the key barrel j, and the clearance space is, one wall of which, as 76 forms a contact surface adapted to be engaged by the ward of a key for reciprocating said plate, and thewallk of which forms a shoulder adapted to be engaged by the side of said ward for rotating said plate. The size of this opening may be varied at will to change the position of the contact 73 relative to the key barrel, thus varying the throw or the reciprocatory movement of the plate with a key having a ward of fixed length, or necessitating a change in the length of the ward in order to secure uniformity in the throw, or reciprocatory movement of the said plate. The shoulder 70 projects substantially radially of the key barrel j and the contact surface 76 extends at substantially right angles to said shoulder, an arrangement which secures the application of suflicient force to the said plate to reciprocate it and subsequently rotate it. Opposite the contact 70 is a shoulder 70*, adapted to be engaged by a key to restore the plate 72, to normal.

By the construction of the guard plate above referred to, to change the combination of the lock, it is merely necessary to substitute for a plate in which the contact surface 76 is of one radial distance from the aXis of the key barrel, a plate in which this surface is of a different radial distance from said axis, thus requiring the use of keys having wards differing in length in the same proportion as the radial distance between the contact surfaces of both plates.

The plate It and cup 0 are provided with cooperating means by which said plate is normally locked in relation to said cup. This means comprises a bolt socket c in the casing c, and a short bolt it carried by, or formed integrally with, the plate It, and adapted to enter said socket, the spring a being always in tension and tending to normally project said bolt outwardly. This bolt is withdrawn from the socket by the reciprocatory movement of the plate it, and

before the plate may be rotated to withdraw the bolts d cl, it is necessary that this bolt it shall be completely withdrawn from said socket. To insure against the actuation of said bolt by a key having a ward of a length greater than would just bring said bolt If within the cup 0, I provide the cup 0 with a bolt opening 0 preferably diametrically opposite to the socket 0, and also provide the plate it with a second bolt 7L5 adapted to cooperate with said socket, this bolt being normally spaced away fro'm the cup 0 for a distance equaling the proper quantity of movement of the plate h to withdraw the bolt h from its socket c. If the movement of the plate under a key be insufficient to fully retract the bolth the plate 72, will remain locked, while if the reciprocatory movement of the plate be more than enough to bring said bolt just within the cup 0, or in other words, if the ward of the key be too long, the bolt k will be thrown into the socket 0 again holding the plate against movement. Hence, to actuate the lock, it is necessary to have a key, the ward of which is of exactly the right length, and various combina tions may be secured with a single guard plate by changing the radial position of the shoulder k To limit the rotary movement of the plate f, I provide said plate with a peripheral channel P, which channel has seated therein an abutment 0 carried by the cup 0. The construction heretofore described enables me to use a very shallow cup, so that by drawing the head of the hasp b upwardly, as at Z), a shallow lock may be secured. This shallow lock has the advantage that it may be used in connection with what is known as a surface keeper plate, or one having a central opening therein through which the cup is adapted to project, the portion of the keeper plate about said opening being drawn up so as to allow clearance between the plate and the trunk or chest body suflicient to accommodate the bolts (Z cl. This keeper plate is shown at m in the accompanying drawings, the drawn up portion thereof being indicated at m.

The operation of the herein described lock will, in the main, be apparent from the foregoing description, but in order to make the invention more clearly understood, a detailed description of the operation of the bolt controlling and guard mechanism will be given.

When the parts are locked, they will be in the position shown in Figs. 1 to 3. When it is desired to release the lock, the key is inserted in the key barrel. As the key is inserted, the wards will engage and enter the portion of the clearance space is to the left. The key is then turned to the right, Fig. 1, the end of the wards engaging the contact surface 7.2 and reciprocating the plate It to an extent to completely withdraw the bolt 7& from the socket 0. If the wards of the key be of the proper length, this will occur just as the side of the key contacts with the shoulder as the arrangement of the surface 7: is such as to have the maximum movement of the plate defined by the junction between the surface 76 and the shoulder 70 The slots 71/ and k studs 9 g and way Z? will permit this reciprocatory movement without placing any limitation thereon. If the wards of the key be too short, the plate It will not be reciprocated sufficiently to cause the bolt h to clear its socket 0', while if on the contrary the wards of the key be too long, the plate would be reciprocated to an extent to cause the bolt k to enter the socket 0 prior to, or substantially with, the engagement of the side of the key with the shoulder 70 and thus cause the key to lock the plate It against rotary movement and hold it in this locked position. The movement of the plate under the key when releasing the lock is against the tension of the spring 2'. Assuming that the correct key is used, and the Plate h is reciprocated thereby to the proper extent, the key may be further turned, rotating the plate 72. and with it, through the slots h if and studs 9 g, the plate The movement of the plate f will through the studs f F, withdraw the bolts d d, and permit the hasp to be raised. The J springs e 6 will permit the retraction of the bolts d d to the full extent. Immediately upon the unlocking of the bolt, and raising of the hasp, the key may be turned in the reverse direction, the shoulder 76* to the left of the clearance space is being engaged by the key and causing the movement of the key to restore the plate It and with it the plate f, to normal. Assoon as the bolt it comes into alinement with the socket 0, the spring a will force said bolt into said socket and again lock the plate 71. in its normal position. The springs e 6 with the movement of the plate f, will again project the bolts cl cZ outwardly, preparatory to the succeeding operation of the lock. This last de scribed operation is characteristic of an ordinary snap lock, and is essential to my invention only when my invention is applied to this type of lock.

By the construction herein shown and described, I am enabled to produce a lock which may be so finely adjusted as to possess a high factor of safety, and one in which the compound movement of the guard plate is such as to prevent the manipulation of the look by any means other than a key having a ward corresponding in exact dimensions to that in connection with which. the lock is designed to be used.

I have, in the accompanying drawings shown a bolt controlling mechanism which is satisfactory for a lock of the character shown, but this mechanism may be varied without departing from the spirit and scope of the invention. The essential characteristic of my invention is the guard plate having an alternate reciprocatory and rotary movement, normally locked in relation to the cup, the reciprocatory movement thereof disturbing this normal relation and per mitting a subsequent rotary movement for actuating the bolt controlling means.
